WATER-SAVING MINING-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 675,583, dated June 1901- Application filed na ai, moo. Serinlllo. 18.4%. on model.)

To all whom it may concern:

Be it known that I, FREDRICK AUSER, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented anew Water-Saving llrlining-Blachine, of which the following is a specification.

My invention is intended to be used in connection with the ordinary goldsaving sluicebox; and the objects of my invention are to receive all the gravel and water that passes through the sluice-box; second, to provide facilities for saving this water and atthe same time carry off and dump the gravel; third, to return the water thus saved to a receptacle from which it can again be run through the sluice-box. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a longitudinal central section through the device. Fig.,2 is a transverse section on line y 1 Fig. 1.

Similar letters refer to similar parts throughout the two figures.

From the sluice-box D the water and gravel fall onto an endless belt A, which is securely fastened to twoendless chains 15. At regular distances rit'lles a are attached to the endless belt A. This endless belt and rillies are of sufficient width to travel along with the endless chains over the end drums b Without any interference with the two side protectors c. These side protectors contain various appurpose and attached from the top of the side protectors c to the sidetrames E. The water flowing through the apertures and striking this covering is precipitated into box H, which is nothing more than the interior of the frame i This frame is placed at a slight incline to allow the Water confined to box 11 to run into tank F, from which it can be re used in the sluice-box D, first above men tioned. The apertures c are commenced in the side protectors O at a height sulliciently above the endless belt A to preclude the possibility of any of the gravel received from the sluice-box 1) making its exit with the water through said apertures. 'lhe gravel is carried along by means of the endless belt and rillles to a point on the end drum, where the chain, belt, and rillles commence their under movement or return journey, when the gravel must of necessity drop off from the belt, and, if so desired, can be taken by means of a chute to a more distant dumping-place.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

The combination of a sluice-bore and an endless traveling belt with rillles; side proteeters with apertures, said side protectors having on their outsides covers to keep the water flowing through said apertures .confined to box bclow-all in combinatiou'avith means for saving water in a receptacle substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FREDRICK AUSER.'
